Breathing was held intentionally or unintentionally.
The one reading was naturally Hewinia.
She had sensed earlier that Bai Wei would occasionally leave her body, even when he was not sealed.
And when Bai Wei left, he couldn't "monitor" Hewinia.
Hence, Hewinia knew she had to make good use of this time to do things that Bai Wei shouldn't know about.
Like... now.
What Hewinia was currently flipping through was the ancient book fetched from the library yesterday, containing information about "Visas."
To deal with this troublesome entity inside her, she at least needed to know who he really was.
So, today she had purposefully pretended to be very tired, waiting for the night to fall asleep without arousing Bai Wei's suspicion, gambling that Bai Wei would leave her body to do something else at this time.
And indeed, her gamble proved right.
She truly felt Bai Wei's departure, and he had been gone for quite some time.
But she couldn't feel happy about it.
